摘要：

Collisions of He+- and Ne+-projectiles with He at impact energies between 90 keV and 800 keV were investigated. Relative excitation cross sections for magnetic sublevels of He-4(1) D were determined using level-crossing techniques. Absolute excitation cross sections sigma(m) of the Zeeman-sublevels are given using He-4(1) D cross sections from earlier measurements. The results show strong variations of the cross sections sigma-0 and sigma+/-1 with a quasi-oscillatory behaviour. sigma+/-2 is much smaller than sigma-0 and sigma+/-1.
